The A420-065714-00 is a base cover assembly manufactured by Guardian Electric. It is an oval shaped metal box with a metal lid and painted with grey epoxy. It is designed to be used with the Guardian Electric A420 Safety Switches and contains the contact assembly, mounting fasteners and a base contact finger with a strain relief. The base contact finger helps to reduce wire chafing, and the strain relief ensures that the wires are securely attached to the box. A rubber seal is provided to ensure the box is sealed and dust-proof. The box also has two captive mounting screws, with one on the inside and one on the outside, to make installation and removal easy.
